Accelerate Cloud Migration with Azure Arc Resource Discovery in Azure Migrate (Preview)

Author: Snehith (Microsoft)

Overview

Azure Arc is widely used for managing hybrid IT estates, allowing organizations to extend Azure services to workloads running anywhere. With the new preview capability—Arc-based discovery in Azure Migrate—you can quickly evaluate migration readiness and savings for Arc-enabled servers and SQL Server instances without needing new on-premises deployments.

What’s New

  • Arc-Based Discovery leverages your existing Arc-enabled resources for migration assessment.
  • Instantly assess migration readiness for Azure targets like:
    • Azure Virtual Machines (VMs)
    • Azure SQL Database
    • Azure SQL Managed Instance
  • Gain insights into savings for different migration strategies without additional infrastructure.

Getting Started

  1. Go to Azure Arc Center and create a migration project.
  2. Scope your Arc-enabled resources by subscription.
  3. No extra on-premises setup is needed—all assessments use data already collected by Arc.

Key Features

  • Migration Readiness Assessments: Identify readiness issues and recommend suitable Azure SKUs.
  • Business Cases: Compare current total cost of ownership (TCO) with Azure and highlight savings via Reserved Instances, Azure Hybrid Use Benefits, and Extended Security Updates for end-of-life workloads.
  • Sustainability Impact: Estimate environmental benefits of migration.
  • Custom Assessments: Optionally, deploy the Azure Migrate Collector VM extension to gather performance data for more accurate recommendations.

Resources

Summary

Azure Migrate’s Arc-based discovery simplifies cloud migration by streamlining business case analysis and readiness assessment for hybrid environments. Users can plan and optimize migrations with actionable insights directly from their existing Arc-enabled resources.
